• The basic principle of piezoelectric ceramic buzzer and the application of piezoelectric buzzer

  Piezoelectric ceramic buzzer is a device used in piezoelectric ceramic sheets. It is more common to form titanium and piezoelectric ceramic sheets (pzt) sintered with zirconium and lead oxides. Since the human ear is most sensitive to the audio signal of 3khz, the resonant frequency of the piezo ele

• Principle and quality discrimination of piezo ceramic elements

  The piezoelectric diaphragm works on the principle of piezoelectric effect, which generates mechanical vibration when an alternating voltage is applied thereto; on the contrary, it also generates a voltage signal when a mechanical force is applied thereto. Therefore, the piezoelectric ceramic buzzer

• Detecting method of piezoelectric ceramic crystal

  Piezoelectric ceramic crystal sheets are a synthetic piezoelectric material. When are subjected to external pressure, charges are generated on both sides surface, and the amount of charge is proportional to the pressure. This phenomenon is called the piezoelectric effect. Piezoelectric ceramics have
